The Umbrella singer and her 19-year-old boyfriend - who has been charged with felony assault and making criminal threats following his alleged assault on her last month - are said to have filmed themselves engaging in a series of "kinky" acts.

A source told America’s Star magazine: "Chris and Rihanna enjoy an aggressive love life that would shock many people. Rihanna loves dressing up - including as a dominatrix - and role playing.

"They both have kinky sides."

Rihanna - who reconciled with Chris shortly after their altercation, but is now said to be taking time away from him to contemplate their relationship - has become increasingly concerned the footage could be made public and is desperate to keep it under wraps.

The source added: "Rihanna has no issues with her sexuality. She can be really out there. But she’d be mortified if her friends and family found this out.
